Complete VRT Guide for Ireland 2025

Everything you need to know about Vehicle Registration Tax in Ireland - from basic concepts to detailed calculations, exemptions, and the complete registration process.

What is VRT?

Vehicle Registration Tax (VRT) is a tax charged by Revenue.ie on vehicles registered in Ireland for the first time. Whether you're importing a car from the UK, Northern Ireland, or elsewhere in the EU, or purchasing a new vehicle from a dealer, VRT must be paid before the vehicle can be legally driven on Irish roads.

VRT is a one-time charge that varies significantly based on the vehicle's characteristics, particularly its CO2 emissions for passenger cars. The tax was introduced to ensure environmental standards and generate revenue for the Irish government, with higher-polluting vehicles paying substantially more.

Who Must Pay VRT?

Vehicle Categories

VRT is calculated differently depending on the vehicle category. Understanding which category your vehicle falls into is the first step in calculating VRT.

Category A - Passenger Cars

Includes cars, SUVs, MPVs, and minibuses with up to 8 passenger seats. This is the most common category and has the most complex VRT calculation based on CO2 emissions.

Category B - Light Commercial Vehicles

Includes vans, pickups, and light commercial vehicles up to 3.5 tonnes gross vehicle weight.

Category C - Heavy Vehicles

Includes trucks over 3.5 tonnes, buses, tractors, and vintage vehicles over 30 years old.

Category M - Motorcycles

Includes motorcycles, scooters, and electric mopeds.

How VRT is Calculated

Step 1: Determine the OMSP

The Open Market Selling Price (OMSP) is the price a vehicle would typically sell for in Ireland on the open market, including all taxes and dealer profit margin. For new vehicles, this is usually the Irish retail price. For used vehicles, Revenue.ie maintains a database of OMSPs based on:

Step 2: Apply the CO2-Based Rate (Category A)

For passenger cars, locate your vehicle's CO2 emissions in the VRT rate table. The emissions figure must be based on WLTP (Worldwide Harmonized Light Vehicle Test Procedure) testing. If you only have NEDC figures, they must be converted using official formulas:

Step 3: Calculate NOx Levy (If Applicable)

Diesel vehicles may be subject to an additional NOx levy based on nitrogen oxide emissions:

NOx Emissions (mg/km) Additional Levy
0 - 60€0
61 - 80€1
81 - 100€2.50
101 - 120€5
Over 120€10

Step 4: Apply Minimum Charge

Each CO2 emission band has a minimum VRT charge. Even if the percentage calculation results in a lower figure, the minimum charge must be paid. This particularly affects lower-value vehicles.

Example Calculation

Vehicle: 2022 Volkswagen Golf 1.5 TSI

  • OMSP: €30,000
  • CO2 Emissions: 115 g/km (WLTP)
  • Fuel Type: Petrol

Calculation:

  • CO2 band 111-115 g/km = 15.25% VRT rate
  • VRT = €30,000 × 15.25% = €4,575
  • Minimum charge for this band: €305
  • NOx levy: €0 (petrol vehicle)
  • Total VRT: €4,575

  2. Gather Documents: Vehicle registration document, proof of purchase, insurance certificate, valid NCT/DOE (if applicable)
  3. Book Appointment: Schedule an appointment at an NCTS center (National Car Testing Service)
  4. Vehicle Inspection: Bring vehicle for VRT inspection (identity, safety, emissions check)
  5. Pay VRT: Pay calculated VRT amount (card, cash, or bank draft accepted)
  6. Receive Registration: Get Irish registration plates and certificate
  7. Display Plates: Fit Irish plates within specified timeframe

Common Issues and Solutions

OMSP Disputes

If you disagree with the OMSP assigned by Revenue.ie, you can appeal the decision. Provide evidence of comparable vehicle prices in Ireland, condition reports, and professional valuations.

Missing CO2 Data

For older vehicles without recorded CO2 data, Revenue.ie may use manufacturer specifications or assign a default value. Contact the manufacturer or check European type approval documents.

Modified Vehicles

Vehicles with significant modifications may require additional inspection or documentation. Engine swaps, body modifications, or conversion work must be declared and may affect VRT calculation.

Import from Northern Ireland Post-Brexit

Vehicles from Northern Ireland now require additional customs documentation. Ensure you have proof of origin and VAT/customs clearance before attempting VRT registration.
